THE IRZ TMS DOWNHOLE MONITORING SYSTEMS ensure sustained real-time monitoring of all practically required downhole parameters of electrical submersible pump (ESP) system, such as pump intake pressure and temperature, motor oil/winding temperature, motor vibrations, current leakage, and pump discharge pressure, as well as up to 24 optional parameters depending on additional equipment in use with the sensor (i.e. anti-scaling electromagnetic unit, motor RPM measuring unit, etc.)
Data provided by IRZ TMS helps preserve ESP, increase pump run life, and optimize oil production. High reliability of new downhole monitoring system is ensured by two standalone electronic modules set in the sensor: active one in operation, and the second on standby mode. Should the main module fails, the system will switch over to the standby module, either by operator’s command or automatically, assuring trouble-free operation of the entire system.
